SLUG.

Specification of Letters Patent.

Patented Jan. 20, 1920.

Application led September 4, 1919. Serial No. 321,508.

To all whom z't may concern.'

Be it known that I, EDWARD L. CUsHiIAN, a citizen of the United States, and a resident of Miami, in the county of Dade and State of Florida, have invented certain new and useful Improvements in Slugs, of which the following is a specification.

My invention is an improvement in matrices for linotype o1l intertype and similar machines for preventing blurring or smutting of the sheet Where several quad lines occur together.

In the drawings:

Figure 1 is a sectional View of the slug;

Fig. 2 is a section on line 2-2 of Fig.v 1;

Fig. 3 is a longitudinal sectionof a linotype slug embodying the improvement; and

Fig. 4 is a plan view of the slug.

As is known in printing where there are several lines of quads occurring together, the sheet is very likely/to be blurred or smutted by its engagement with the surface of the slug.

In the present invention means is provided on the slug for holding the sheet out of contact with the base surface of the slug, that is with the base level from which the formed characters arise. This means isa series of points or raised lines 1 formed on the face of the slug 2 at intervals sufficient to support the sheet between the raised printing surfaces 3. These `elevations support the sheet and prevent it bellying against the base surface of the slug where it would become blurred.

The elevations are formed by a suitable depression 4f in the matrix 5 otherwise of usual construction, and they are spaced from each other a distance corresponding to the distance between centers of the raised printing characters.

It will be understood that these elevations 1 are of less height than the raised printing characters 3, so that the said elevations will not be inked, and hence will not print even when they are engaged with the sheet.

I 4claim A f 1. A slug for linctype or intertype machines, having projections raised above the general level of the face of the slug where printing characters are omitted for the pur pose specified.

2. A slug for linotype or intertype machines, having projections raised above the general level of the face of the slug where printing characters are omitted for the purpose specified, said projections being of less height than the printing characters and being spaced apart a distance corresponding approximately to the spacing of centers of the printing characters.

3. A slug for l'inotype or intertype machines, having projections raised above the general level of the face of the slug Where printing characters are omitted for the purpose specified, said projections being of less height than the printing characters.
